MIC5213-1.8YC5 TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5213-1.8YC5TR is a µCap 80mA linear voltage regulator housed in the Teeny SC-70 package. It provides a fixed 1.8V output with better than 3% initial accuracy and operates within an input voltage range of 2.5V to 16V. The device features very low dropout voltage, typically 20mV at light loads and up to 600mV at maximum load. Quiescent current is minimized to extend battery life, dropping to nearly zero when disabled via the logic-compatible enable pin.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the ordering suffix 'YC5' corresponds to the lead-free Teeny SC-70 package variant as documented in the manufacturer's official datasheet. Confirm the specific output voltage designation matches the required 1.8V specification for your circuit design. Ensure compatibility with the specified operating temperature range before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring minimal board space due to its compact Teeny SC-70 footprint. It is suitable for designs needing tight line and load regulation with low quiescent current consumption. Consider the thermal resistance characteristics when determining maximum power dissipation limits under high load conditions or elevated ambient temperatures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MIC5213 series of µCap Low-Dropout Regulators originally manufactured by Micrel, now Microchip Technology. The series is characterized by its small form factor and optimization for use with low-cost ceramic capacitors. It serves as a solution for portable electronics where size and battery efficiency are critical constraints.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include other MIC5213 variants with different fixed output voltages such as MIC5213-3.3YC5TR or MIC5213-5.0YC5TR, provided the voltage requirement differs. Verify pinout compatibility and thermal performance when considering alternative packages like SOT-23-5.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the minimum output capacitance required for stability?

The MIC5213 requires only 0.47µF of output capacitance for stability and is compatible with low ESR ceramic capacitors.

How does the enable pin function?

The enable pin is TTL/CMOS compatible; pulling it below 0.6V shuts down the regulator with nearly zero current draw, while holding it above 2.0V enables operation.
